Exposure to any amount of radiation will result in death or a terminal disease.
When we speak of radiation, we are referring to all types of radiation, including electromagnetic radiation that is a natural, constant
aspect of our lives. This electromagnetic spectrum includes cosmic radiation in the form of gamma rays, X-rays, ultraviolet rays, visible
light, infrared rays, and radio waves. We are constantly bombarded by radiation; life on earth evolved under conditions of exposure to
multiple forms of radiation. Everything in the world is radioactive and always has been. The ocean, the mountains, the air, and our
food all expose us to small amounts of natural background radiation. This is because unstable isotopes that give off or emit ionizing
radiation are found everywhere. Concern arises when exposure is increased beyond the "normal" levels. In these instances, precautions
must be taken to prevent adverse effects on the body. Precautionary methods include decreasing the amount of time you are exposed to
radiation and increasing the distance and shielding between you and the source of the radiation.
